Low 80s too hot?

I've got a Ryzen 7 5700x cooled with a Vetroo V5 CPU Cooler and I've got PBO enabled which gives me a nice boost in Cinebench and CPU score in 3D Mark however temps are in the low 80s. According to AMD max operating temp for this CPU is 90C so I'm within that.

I was temporarily using it with a Wraith Stealth cooler and without PBO enabled I was hitting 83C so about the same as now but with PBO enabled. One of the reasons I upgraded the CPU cooler was to potentially make use of the PBO setting.

If I run it at stock, temps are about 64C so much less than the 83C I was seeing with the Wraith Stealth. Should I just disable PBO and leave that to those on water-cooling or is low 80s ok?
 
That's a very modest cooler - a great improvement in temps and noise over a stock cooler - but not really intended for overclocking.

80C is within limits, which really just means the CPU shouldn't die or shut down to prevent dying - but really it's a higher temperature than you ever want to see on a CPU.

64C is a good temperature - so clearly the winning option is to run the CPU at stock.

Edit: Worth remembering that temps during a heatwave aren't representative of the rest of the year. Not that it changes my advice in this scenario.
 
If you have PBO enabled then it will go up to 90C unless it runs out of power budget first.

So given you are at 83C it is maxing out the power budget before being thermally constrained.

This isn't true at all. Bad advice. It is a perfectly normal temperature. Cinebench is an AVX workload which stresses the CPU loads. Anything less, you either have an amazing cooling setup or you aren't pushing the PBO settings high enough.
 
Well I just installed MSI Afterburner and loaded Battlefield 2042 with the CPU temps set to on screen display. At stock settings with PBO set to AUTO the temps spiked at 77C but were most often in the 60 to 70 range.

It seems Battlefield 2042 creates higher CPU temps than even Cinebench R23 itself. Suffice to say I won't be running with PBO enabled from now on, god forbid what temperature readings I'd get in game with that!

Ryzen 5000 series are very hot running chips but all within design specs. I wouldn't be concerned.

Exactly. All within specs. I like lower than in the 80s but it won't be detrimental to the chip.

83c is fine with PBO on.

My 5800X runs at 80c with a 360mm AIO, i'm perfectly content with that.
 
As I said with PBO set to AUTO (i.e. off) I get max temps of about 64C when running a 10 minute Cinebench R23 multicore run, which is great however in gaming this rises to max 78C which is ok for gaming.

I wouldn't want to run a game with PBO enabled when it already reaches about 83C just running Cinebench R23. I never tried gaming with the Wraith Stealth cooler I used temporarily, but it reached 83C with PBO off.

So its a good thing that I upgraded the CPU Cooler to the Vetroo V5. Well worth the £ 21.32 I paid for it. Keeps my temps at reasonable levels while gaming in particular.
 
Maybe check the bios for a thermal limit setting. I know my msi b550 board has a setting where I can set the max temp (in the advanced pbo bit iirc) I want to get the cpu too when under load etc.

Could be worth lowering it a little if you're concerned about temps.

At the end of the day the whole premise of pbo is basically to allow the cpu to 'overclock' within certain limits and would in turn mean higher temps.

CBR23 will get your temeps way higher than any game would. So, unless you are going to be using your PC to run cinebench and 3d mark, I don't see whats wrong with those temperatures.

I’m finding running Battlefield 2042 at 4K heats the CPU higher than Cinebench R23. In Cinebench R23 max temp 64C but running Battlefield 2042 at 4K up to 80C.

Then its your case airflow thats the problem, it cant handle the GPU heat. What case do you have?

Coolermaster Storm Trooper. Doesn’t constantly run at 80c sometimes between 60C and 70C. Battlefield 2042 is very CPU intensive.

As others have said, what is happening is that the heat the GPU is dumping into the case isn't being replaced with fresh cool air. The CPU is then being cooled with preheated air.

If you can remove all the front drive cages in the case it will help.

Surely if it was the air flow in the case it would remain at a constant 79C but it doesn’t, it can get hot then the next minute it’s under 70C again.

No it wouldn't remain at a constant 79c. What the heck does that even mean? Your case ambient is way higher than your room ambient cause of bad airflow, since it can't handle the GPU heat. Open your side panel and play bf

Cinebench R23 is constantly loading your CPU at 100%. There aren;t many things that load your CPU more than cinebench, and certainly games aint doing that. Especially when you play at 4k. So when your CPU temps climb higher while gaming than when cinebench, it's the case airflow.
